Input Gear Búri Diamond Linear Switches

The Input Gear Buri is a linear mechanical switch designed for users who prefer a smooth, consistent keystroke without tactile bumps or clicks. It suits typists and gamers seeking a clean, quiet experience with moderate actuation force. Its transparent housing also supports good RGB lighting effects, making it suitable for builds where aesthetics and performance matter.

Feel & Sound

The switch offers a smooth, linear keystroke without tactile feedback or audible clicks. Its slightly factory-lubed POM stem reduces scratchiness, contributing to a quieter and more refined typing sound. Bottoming out requires moderate force, providing a solid but not harsh finish to each keypress.

Actuation Characteristics

With an actuation force around 45 gf and a total travel of about 3.8 mm, it balances responsiveness and comfort. The pre-travel distance of approximately 1.9 mm means keys register after a moderate press depth, suitable for both typing and gaming. The longer spring length may affect the feel by offering a more gradual force curve.

Build Quality

The switch features a transparent nylon or nylon-blend housing that enhances light transmission and durability. The POM stem material is known for smoothness and low friction, supporting the linear feel. A longer spring is used, which can influence the force profile and key return. It is rated for around 80 million keystrokes, indicating solid longevity.

Compatibility

It uses a standard 5-pin PCB mount compatible with MX-style sockets, making it suitable for most custom keyboards. The transparent housing supports RGB lighting well. Hot-swap compatibility is unknown.

Trade-offs

While factory lubrication reduces scratchiness, further lubing may be needed for users seeking an even smoother feel. The longer spring and moderate bottom-out force might not appeal to those preferring very light or very short travel switches. Stem wobble and spring ping are unknown.
